This paper presents experimental research on the Computer Numerical Control (CNC) routing of a traditional motif collected from Ţara Bârsei (Transylvania region) using two methods, namely, engraving (Engrave) and carving (V-Carve). The analysis CNC router processes includes calculation path lengths, an assessment processing time wood mass loss, evaluation tool wearing by investigating cutting e...

Currently, the deficiencies of 5G mobile system as an enabler Internet Everything (IoE) applications are stimulating global research activities to focus on sixth generation (6G) wireless system. The potential IoE is enormous and growing exponentially. With dawn fifth industrial revolution, transposing into (IIoE) projects which complex eventuating become a prominent technology for all industrie...

Abstract Beyond setting the stage, Introduction makes three claims about conceptual triangle of rule law, judicial authority and legitimacy. The first is that all are essentially contested interpretive concepts in sense Walter B. Gallie Ronald Dworkin. In their expositions, interpretative nature such nothing to be ‘solved’, rather formulation different conceptions contestation them central func...

Metal-assisted chemical etching (MACE) has emerged as an effective method to fabricate high aspect ratio nanostructures. This requires a catalytic mask that is generally composed of metal. Here, we challenge the general view catalyst needs be metal by introducing oxide-assisted (OACE). We perform with oxides such RuO2 and IrO2 transposing materials used in electrocatalysis nanofabrication. Thes...

extremely low frequency (elf) and radio frequency (rf) electromagnetic field may affect biological systems by raising generation free radicals by decline activities of glutathione peroxidase dismutase or increase in the lifetime of free radicals with inhibited pretreatment of cells antioxidant like that alpha tocopherol. elf and  rf electromagnetic  field maycan damaged dna  with raising level ...

BACKGROUND In biomechanical studies Optical Motion Capture Systems (OMCS) are considered the gold standard for determining the orientation and the position (pose) of an object in a global reference frame. However, the use of OMCS can be difficult, which has prompted research on alternative sensing technologies, such as body-worn inertial sensors. METHODS We developed a drift-free method to es...

recurrent aphthous stomatitis (ras) is known as the most common chronic disease of the oral cavity, which affects a range of 5-25% of the population. ras appears to be associated with some human leukocyte antigen (hla) class ii alleles and haplotypes. this study attempts to survey the distribution of hla-drb and -dqb alleles among iranian ras patients and healthy controls. in order to evaluate ...

abstract  background: the brain response to temporal frequencies (tf) has been already reported, but with no study reported for different tf with respect to various spatial frequencies (sf).  materials and methods: fmri was performed by 1.5t ge-system in 14 volunteers during checkerboard, with tfs of 4, 6, 8 and 10hz in low and high sfs of 0.5 and 8cpd.  results: average percentage bold signal ...

In this study, we explored associations between perception of musical features (pitch, tonality, timing, timbre, and loudness), vocal abilities (singing accuracy, melodic achievement, rhythmic performance), cognitive levels (reading accuracy comprehension, grammar, math) among children ages 6 to 12. Musical were measured using the Implicit Tonal Ability Test. Vocal Cognitive standardized Dutch ...
